I have a partially enclosed patio. There are four arches one of which is the exit to the stairs. Any ideas on how to close the arches to keep the warmth in so we can use the patio in colder weather. We have a fire place in the room and there are currently curtains and mosquito netting hanging on a double rod. Has anyone used insulated curtains or plastic tarp to cover openings. Any advice or new ideas are welcomed and greatly appreciated. Thanks!
